Hi,

I built a ramdisk root partition for redhat 5.2, but it seems to crash as
soon as the kernel jumps to the ramdisk.
The last message I see is:
    VFS: Mounted root (ext2 fileseystem).

I built the ramdisk according to the instructions in docs/bootdisks
(followed it precisely)

Basically, I zeroed /dev/ram, made it an ext2 file system, and then mounted
it on /mnt.
I then created /mnt/dev, /mnt/etc, /mnt/bin, /mnt/sbin, /mnt/lib, /mnt/usr,
and /mnt/var
I populated dev with cp -dpR /dev /mnt
I then copied most of the /bin and /sbin binaries into their respective
locations.  I issued an ldd /mnt/bin/init and copied all of the libraries
required by init.  I stripped out the debug information with objmove from
the libraries and maintained symbolic links.

I then unmounted /mnt and copied the contents of /dev/ram to a file with a
dd if=/dev/ram of=rootfs bs=1k
It said there was a read/write error at this step.  Not sure what caused the
error.

Could someone post a generic redhat 5.2 (intel) ramdisk root partition (one
that can be mounted by the kernel and contains basic binaries)?  I would
really like to try a ramdisk that I know is working.

Thanks,

Probably tried to put too much information into the ramdisk.  Not sure
if the limit is 2Meg or 4Meg.

I can make 4Meg RamDisk images; anything larger, and I get the same type of
problem where the system hangs at boot.
